A simple method for designing high-quality prototype filters for M-band pseudo QMF banks
نویسندگان
چکیده
AbsCmct-This correspondence discusses a new method for designing the prototype filters necessary to implement M-band pseudo QMF banks. This method does not rely on the traditional nonlinear optimization used in past work but rather optimizes a single parameter on a convex error surface, consistently delivering the best equiripple filter possible while minimizing the overlapped passband distortion.

Eigenfilter design of real and complex coefficient prototypes for uniform and nonuniform filter banks
In this study we propose a new method to design Pseudo-QMF prototype filters to implement Near Perfect Reconstruction (NPR) cosine-modulated filter banks. The method is based on the eigenfilter approach, that is simple to implement, but, nevertheless, is very efficient in designing high attenuation prototype filters. The method also allows to design complex coefficient prototypes that can be us...
متن کاملAlternating Analysis and Synthesis Filters: A New Pseudo-QMF Bank
The process of designing a prototype filter for a pseudo quadrature mirror filter (QMF) cosine-modulated bank can require the optimization of a highly nonlinear cost function to obtain its coefficients or the calculation of a spectral factor of a valid 2Mth band filter. This article presents a new method for designing pseudo-QMF banks in which none of the aforementioned procedures are required....

In this paper, a novel technique for the design of two-channel Quadrature Mirror Filter (QMF) banks with linear phase in frequency domain is presented. To satisfy the exact reconstruction condition of the filter bank, low-pass prototype filter response in pass-band, transition band and stop band is optimized using unconstrained indirect update optimization method. The objective function is form...
متن کاملNew algorithm for QMF banks design and its application in speech compression using DWT
This paper presents a new algorithm for designing Quadrature Mirrors Filters (QMF) banks using windowing techniques. In the proposed algorithm the cut off frequency of the prototype filters is iteratively varied such that the perfect reconstruction at frequency (ω=0.5π) in ideal condition is approximately equal to 0.707. The designed QMF banks are used as mother wavelet for speech compression a...
